  (Cp4i)2V (Cpni = C5(iPr)nH5-n) from the reaction of zinc-reduced VCl3 and K[Cpni] in THF at room temperature produces the corresponding zincocenes (Cp3i)2Zn and (Cp4i)2Zn instead. In refluxing THF, the same reactions generate the expected (Cpni)2V vanadocenes. The latter are also formed from the reaction of aluminum-reduced VCl3 with K[Cpni] at room temperature. Reaction of 3 equiv of K[Cp3i] or K[C5Ph4H]

  尝试形成（CP 3i）2 V和（CP 4i）2 V（CP ni = C 5（iPr）n H 5 - n），由锌还原的VCl 3和K [CP n室温下，在THF中生成i ]（CP 3i）2 Zn和（CP 4i）2 Zn。在回流的THF中，相同的反应会产生预期的（CP ni）2 V Vanadocenes。后者也是由铝还原的VCl 3与K [CP n我在室温下。3当量的K的反应的[CP 3I ]或K [C 5博士4 H]用的VCl 3在THF中产生（CP 3I）2 V和（C 5博士4 1H）2 V，分别，而其中K相当于反应[CP 4i ]生成（CP 4i）2 VCl。这些实验表明，每当从还原锌的VCl 3中合成钒钒时，新世烯都是中间体，但只有在使用某些环戊二烯基环和温度条件时，才会分离出锌配合物。（CP3i）2 V发现金属驻留在晶体学施加的反转中心上，平均VC（环）距离为2.274（9）Å；异

  The reaction of (pi-C5H5)TiCl3 with KC5Ph5 (4-Ph) in THF gives (pi-C5H5)(pi-C5Ph5)TiCl2 (5-Ph). (pi-C5H5)(pi-C5Ph4H)TiCl2 (5-H) can be prepared analogously. An X-ray diffraction study on 5-Ph has been undertaken. The Ti-C bond lengths for the C5Ph5 group are considerably longer than those for the C5H5 group; the averages are 2.53 +/- 0.03 and 2.39 +/- 0.04 angstrom, respectively.

• New syndiospecific catalysts for styrene polymerization

  (Eta5-Tetramethylcyclopentadienyl)-, (eta5-tetraphenylcyclopentadienyl)-, (eta5-(diphenylphosphi-no)tetramethylcyclopentadienyl)-, and (eta5-(trimethylsilyl)tetramethylcyclopentadienyl)titanium triisopropoxide have been synthesized and characterized. Their catalytic activities for syndiospecific styrene polymerization have been compared with the reference compound (eta5-cyclopentadienyl)titanium triisopropoxide. (Eta5-Tetramethylcyclopentadienyl)titanium triisopropoxide is the best catalyst precursor, giving rise to catalysts having the highest activity to produce polystyrene with the highest syndiotactic yield and molecular weight.
